Ok, just to add to the original email - the system has been stable since I rebooted a couple of days ago, until this morning when I got the following:

Hi, Experienced this strange crash this morning and was wondering if anyone could tell me what it might be. The system in question was running under vmware but with a physical hard disk. Originally I thought it might be a memory problem so I ran memtest86+ and checked the swap with mkswap -c but neither reported any problems. The kernel is a clean compile of version 2.6.21 with no modules loaded. /proc/version shows: Linux version 2.6.21 ([EMAIL PROTECTED]) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #2 SMP Wed Jun 13 10:36:40 BST 2007 Outputs from other /proc/xxx as given in the bug reporting guidelines are at the bottom of the email. Full text of the logfile is below. It also includes all the messages spat out by the kernel when I rebooted it afterwards, incase that will help diagnose the problem.
